If you don’t believe that your cause is just and is supported by your people, can you fight? No. You can fight to survive (which will sometimes mean surrendering) but you won’t fight to win.
But if you believe in your cause and know you have support and trust and that people are praying for you, that’s a whole different thing. And that’s what this means.
Oh good grief.
